well im cleaned out of money right now, the port and polish of the plenum, throttle, lower, and runners did real nice, changed up the sound to a more deep roar.

i havent dyno'd yet but i can def feel mid rang power and more tq in the 1st 2nd gears. i have to hold off on the q45 TB. maybe in like a couple weeks.

also there was a small half inch plastic thing in one ov my valves!!! thats what slowed me down on the dyno

Not necessarily. TOO large of a TB can actually slow the airflow into the engine and not properly fill the combustion chamber. So yes, you CAN go too big with a Throttle body and lose power as a result.


I don't know what it would do in this case though
